TYPE-CASTING MACHINE.

To all whom z't may concern.-

Be it known that LSHAN'KER ABAJI BrnsEr, a subject of=the Kingof Great Britain, residing'at London, England, have invented certain new and useful Improvementsin Type Gasting Machines, of which the following is a specification. v

This invention relates to improvements in type casting machines, and has reference to machines for casting single types Machines of this kind at present -in-genera1=use According to one made up =01 a set of two L shaped parts mounted :on a swinging frame by the action of which they-are made to open and close. Such an arrangement is Very costly and a fresh set otmold parts is required foreach size of type body, and as the mold *has to move a good distance away from the metal pot, the speed of th'e *machlneus very limited. Machines of the other known kind work more rapidly 'but have the great defect =of produc1ng burs on the'cast type and therebyaafl'ect its accuracy owing'to the type body forming pieces and .other mold parts constantly sliding'between two' fixed parts-of the mold. In my present invention have entirely overcome the above defects by constructing :the principal parto'f the'mold to consistxof a body ipiece, an adjusting piece and :a wall piece "which practically -iorm'a mold and when the partsvare once adjusted *to the required body "and set width of-the type retain the form and have no internal slidingrparts. The moldls closed according to my invention 'by a movable platform :or: a

' cover plate upon-which the types arecast and preferably remain till they are pushed-on to the :recei-ving platform. It will be observed that the'constru'ction and operation of my mold differs radically from those previously proposed and I believe I-am thefirst person to provide a machine having such a "mold consisting of non-rubbing parts and provided with a very simple body forming'or adjusting piece. Among other important features 1 of my invention :m'ay 'be 'mentioned means -whereb y the cast types are held down upon the platformior cover plate'after cast- .ing, means whereby they are transferred from =the platform or cover plate to a -receiving i platform or channel. The preferred means :for iholdingt'he types down upon the Specification of Letters Patent.

cover plate comprises a nick or projection forming member upon the platform or cover :plate cooperating with an extrudingdevice "and while they are being packed and preventing wear upon all relatively =sliding= zparts.

Referring to these drawings and particularly to Figs. 1 to 8 a mold is formed (see Figs. 3 and 4) by means'of an adjustable block 1, aside wall 2 and a body piece 3 and the mold is closed by a cover plate or platform 4 ,uponwhich the types are cast. Attached to the platform4 a slotted plate or hook shaped member 5 is provided and the slot 5 in this plate is closed on. one side by the side wall 2v of the mold, and thus forms a part of the tang or break mold, the

other part of this tang mold being formed by the adjustable tang plate 6 which is closed, upon one side by the mold member 2 and upon the other side by a plate 7. The tang plate 6 is adjusted by means of the screw 8 so that the size of the orifice between the tang mold. and the type mold readily understood upon reference to Fig.4

ofthedrawings. The platform 4 is provlded with a nlck forming 5111 12 Wl11Cl1 fits into a corresponding recess in the mold body piece 3. The end of this pin is provided, with a wedge orcther groove 13 so shaped that while a cast type can be moved longitudinally of the nick forming pin it cannotbe lifted off the platform 4 by reason of the small dit or projection 14 shown in Fig. 7 being engaged in the groove 13.

Set width adjustment of the mold is effected by the bell crank lever 15 which engages at one end in a recess 16 in a slidable member 17 associated with the body piece 3 while its other end can be adjusted by means of the nut 18 which cooperates with the screw 19 pivoted at 20, an abutment 20 cotuated by the cam 31 and spring 32. The

operating with an interposed matrix or gage plate 57* to control the setting of pieces 3 and 17 to give the correct set width of the mold and'the type, as will be readily understood upon reference to Fig. 1 of the drawings.

Body size adjustment is effected by changing the body pieces 3 and adjusting the block 1 to it by means of the adjusting screw 21. The top part of the mold is arranged. to swing out about the pivot or hinge 22 so as to render this body piece and other internal parts of the mold accessible. The block 1, and the platform 4 upon which the types are cast, are shown provided with water itwill, be appreciatedthat other parts may tally away from the mold by means of the link 25 actuated from the cam 26 through the lever 27. The side wall 2 then moves ,slightlyto open the mold so as to prevent rubbing. This slight movement is effected by thebcll crank lever 28 which is connected by the connecting rod 29 to the lever 30 acplatform 4 now moves down under the infiuence of the grooved cam 33 and connecting lever 34. The platform 4 moves downward until the typewhich is connected to it by the engagement of the dit or projection 14 in the groove of the nick forming pin 12 v .and also by the engagement of the hook shaped member 5 Withitsv tang or; break piece,

is opposite to the receiving channel 35. A pusher or packer 36 then operates to push the type into the channeland this pusher is actuated by-means of a lever 37 actuated by a grooved cam 38.

Afterthe pusher or packer has operated to push the types into the channel or receiver 35, it recedes again, the side wall 2, platform 4 and ma'trixholder return to their normal positions ready for the next casting operation, and it will be observed that .the foregoingoperations are effected without any rubbing action of the mold parts taking place. The type chany nel or receiver 35 is formedby a stationary platform '39 and an adjustable cover v4,0. The platform 39 is provided with a bead or qribz4l and nick cutters 42 adjustable about pivots-43 by means of the screws 44. The

-cover 40 has a spring catch 45 at one end and at this end the cover is narrowed somewhat to allow clearance for the end of the pusher or" packer 36 when a type of small body size is being. dealt-with. The spring catch operates ,-to hold the last type packed n posltion. During the packing operation i,24o,ies

I knife end 46 of the bead 41 "and'the severed dit s or projections fall down the channel or passage 47, while further nicks are cut in the type as may be desired by means of the nick cutting devices 42 on lever 4.2 past which the types are pushed. The cutting ends of these cutting devices preferably consist of teeth or serrations arranged in tandem, the

foremost tooth being slightly lower than course be provided and by means of the adj usting screws 44; any or all of them can be adjusted out of cutting position or in position to cut nicks to any required depth. Duringthis nick cutting operation the cast types are'guide'd by means of the bead ll with which-the cast nick in the type engages. The tang or break piece of the type is removed by means of the tang separator 48 which is operated as the platform & 'moves back to the casting position by the lever 49 actuated by the lever 3i which actuates the platform 4.

It will be observed that as the set width of the type varies the edges of the type and of the tang piece which are nearest the packer will alter their relative positions as will be seen upon reference to Figs. 7- and 8 which illustrate types of different set widths. To allow for satisfactory packing of these types the pusher or packer 36 is constructed in two parts so that the part 50 of the packer which comes in contact with the tangs or break pieces of the types is adjustable so that the part of the pusher which engages the type body and the part which engages the tang or break piece both make contact simultaneously. The pusher ends are varied and set by varying and setting the distance between the jaws 51 and 52 according to the set width of the particular type being dealt with, and this setting may be arrived at by'interposing the matrix between the jaws 51 and where only one kind of matrix is used, but various kinds of matrix can be provided for by providing fitting or gage members such as 5%, adapted to be interposed between the jaws 51 and 52 together with 'thema-trix employed. When it is desired to change the body size the matrix will have to be lowered or raised according as to whether the new body size is smaller or larger than the preceding one. In order to'en'able this to be readily effected, the end of the body piece which determines the body size is inserted between jaws 53 and 54, which jaws are then adjusted thereto. To allow for double letter matrices distance pieces may be employed in conjunction with the body pieces. Fine adjustment may be provided for by means of a. micrometer head 55.

The matrix carrier is illustrated in Fig. '5.

The matrix 9'is mounted in the carrier and the screw 56 screwed up until the end of the bell crank lever 58 jams the clamp plate'57 and matrix 9 firmly in place. The matrix carrier as a whole slides into position upon guides 59. The matrix can be adjusted in position in the carrier vertically by means of an adjusting screw 60 which operates to cause the whole of the interior part of the carrier to slide'relative to the outer frame 61. In the drawing a matrix of the lino-type character is shown with no side margins and when such matrices are used fitting strips 9 and 9 are employed. When however electrotype matrices are employed with side margins the fitting pieces 9 and 9 are removed. It will be observed the construction of the mold could be modified in several ways without departing from the spirit of the invention. I

In Figs. 9, 10 and 11 I have illustrated a modification of the mold forming members. In this case the mold moves bodily fr'omthe mold closing platform 61 which remains stationary with the cast type attached to it by means of the undercut nick forming pins indicated by the numeral 62. The mold parts are carried in a plunger device 64: and these mold parts comprise body members 65 and. '66 the member 65 being vertically adjustable by means of the screw '67 In operation in this case after a type has been cast, the plunger device 64 rises and leaves the type on the platform 61 and the pusher 68 then pushes the cast type into the receiving channel 69. The pusher 68 in this case consistsjof two members 68 and 68, the member 68" engaging the tang or break piece. When the pusher has pushed the type up to the obstruction 70 on the receiving platform, the spring 71 compresses and the obstruction 70 causes the tangs or break pieces to be broken ofi. Figs. 12 and 13 show a means for casting cored quads or space type. In this case instead of a matrix a core 72 is provided attached by a narrow neck 73 to a core holder 74:. In other respects the arrangement and operation is precisely similar to that described in relation to Figs. 18, but the matrix holder (Fig. 5) remains stationary. The types are cast and then carried down by the platform 75 to which they are attached by the nick forming pins 7 6 and the hook-device 77 attached to the platform 7 5 and a pusher then operates to push them into a receiving channel. Fig. 14 shows how the hook device for engaging the tang or break piece of the type can be dispensed with and the types held to the platform 7 8 by the pieces 7 9, 80, which are cast with them and which are so shaped as to insure the type being incapable of rising ofi the platform. The piece 80 is 'a small ""dit or projection which is removed in the manner previously described a-nd of course the piece 79 being on the tang or break piece is removed together with the tang or break the-tang or break mold may be adjusted with the adjustment for set width. In this case the body piece 96,015 the mold has connected to it anotherpiece 97 which moves with it and thus adjusts the set width of the tang mold simultaneously with'the adjustment for the type mold, proper, thus obviating the necessity for adjusting the ends of the pusher or packer. In Figs. 18, 19, 20 and 21 the arrangements to cause the type to be carried down with the platform-and then delivered to-a receiving channel differ somewhat. The types are cast on the platform as before. The platform designated by the numeral 98 is mounted in a block 99 which slides bodily in the direction of the arrow at with the platform after the type has been cast and thus the mold cavity 99 is open. Instead of the platform moving down with the types on it the types are pushed out by means of a plate 100 (see Fig. 21) which forms part of the tang or break mold and I after the casting operation descends. Acting. in conjunction with this plate a finger 101 moves from the position shown inFig. 18 by means'of a suitably actuated slider 103 to t e position where its end 102 is over the character portion of the type. This fingerlOl and the plate 100 descend with the dome 100 and push the type on to the end of a stationary platform 104.

The block-99 then moves back to the casting position carrying the plunger 98 with it and the shoulder 105 pushes the type along the receiving platform 104 and closes the mold for the next operation. In order to prevent rubbing a spring 106 is. interposed between the lug 107 of the'block 99 and the platform 98 so that immediately the casting pressure is relieved the platform 98 moves slightly away from the mold. For purposes. of strength ribs 108 are provided and the end of the stationary receiving platform has portions cut away to accommodate these ribs. In Figs. 22 and 23 I have illustrated a modified device for cooperating with the nick forming pins for carrying down the casttype with the platform. The types are cast on the platform 109 and'are held thereto by the drag forming members 110 as before. Instead however of the hook like device previously. described as connected to and moving with the platform I provide a plate.

111 which here again forms part of the tang or break: mold and when the platform 109 descends the spring 112 causes the plate 111 to assist in holding the type down upon the platform and at the same time this plate wipes the front of the nozzle plate 113.

other side being formed by the slidable mem ber 117 mounted on a downwardlyprojecting portion of the member 114. A bifurcated body adjusting piece or gage member 119 is interposed between the top of the block 114 and the wall 118 of the block 115. The body adjusting piece or gage member 119 is interchangeable and in adjusting the body sizeof the mold the correct'bodypiece or pieces 119 is inserted and the block 114 adjusted up to it by means ofthe screw 120.

In order to vary the stroke of the pump operating plunger 121 to permit of the amount of metal delivered to the mold being varied as required according as small or large types are being cast, I provide the differential levers 122 and 123 and I provide an adjusting member 124 slidable in guides 125, and this member moves by reason of the adjusting screw 126 beingengaged with the internally screw threaded sleeve 127 when the operating handle 128 is turned as will be readily understood upon reference to Figs. 1 and 2 of the drawings. The pump operating plunger is actuated by reason of the cam 129 cooperating with the lever 122 and the motion of this lever is communicated to the lever 123 by the connecting buffer 130 which is vertically slidable in the horizontally slidable member 124. It will be obvious that the stroke of the pump operating plunger 121 will depend .upon the position of the connecting buffer 130 between the levers 122 and 123. v
